To all whom it may cuuu rn:

Be it known that l, )lon'rmit': FlLH'i-ZN- "UL-u, a citizen of the ['nited $tatt's'. and a residentof Conway, in the county of Faulkner and btate of Arkansas. have ivented certain new and useful lmprovelnens in liotar Engines, of whie-h the following is a speeilieation.

.\l invention is an improvement in rotary engines. and eonsists in certain novel eontruetions and combinations of parts as will he here-inal'ter des rihed and elaimed.

Referring to the drawings, forming part hereof. Figure I is a vertieal eetion through the engine. Fig. 2 is a plan view of the rotor and supporting frame, and Fig. I; is a detail perspeetive view of the inlet pipe and the adjustable tongue.

in the present embodiment of my invention, the rotor comprises a disk (I seeured to a shalt u, journalled in hearings II. on a supporting frame I). The peripher v ol the disk at the sides thereof is provided with radial annular llanges u, and a plurality ol" radial blades, wings or vanes a are arranged transversely of the periphery of the disk he tween the flanges, the said vanes extending from flange to flange and heing ol' lzfih't'l h ight than the said flanges, as shown in Figs. i and 2.

.B'aekets b projeet upwardly from the I ante B and supported u ion the upper ends ul' the brackets" is the motive fluid inlet pipe (Y. the said pipe heing reetangoh.r in eross section, a shown in Fig. 23, and the lower face of the said pipe :uljaeent to the fr e end 'Ulll't'fll is eurved to eor espond with th path of travel of the free ends of the lnlades It".

The upper face ol' the pipe at its free end is provided with an upwardly projecting flange 1', having spaeed slots e, for a purpose to he hereafter deserihed and the flange is blurred against the pipe. h v ahutments 1". The lower face of the pipe (I is also provided wit. longitudinal grooves c for reeeiving the llanges ol' the disk, and the HJltl pipe is o arranged with relation to the disk, that the lower grooved l'aee thereof is spaced apart a slight. distaisze from the free ends of the tongues, as shown in Fig. l-

A directing tongue 1) is adjustahlv connected with the free end of the inlet pipe, the 1 easing having an iuottve thud having one laee t'tHYtt to eorresaid tongue comprising open hottom, as shown Hi lugs] and 35, and

.having its sides provided with grooves (l for;

thr ugh the inlet pipe reeeiving the flanges ol' the di k. Th inner end of the easing i provided with an upwardly projeeting flange d hraeed against the ea ing h ahutments (1 and provided with openings 1/. registering with the slots hel'ore deserihed when th flange ol' the tongue nlnlt against the flange ol' the inletpipe. Bolts 1! traverse the sl ts and openings an nuts :1 engage the holts l'orseeuring the parts t-rgether.

The inner url' 'e f the upper fare of the tongue is eat 2:. rs shown at ii in Fig. l to properly lielleet ttt dil'tt't the motive 'llltid against the rear hir s ol' the hlades or va re and the extreme outer end of the tongue is -urved eoneentri aflv as at (F with the disk and such eurveo. tn'l aee is adapted for engagelnent the free ends of the tongue during the rot: tion of the disk.
